The catenary degree of monoids of product-one sequences

Jun Seok Oh

Let $G$ be a (multiplicatively written) finite group. A sequence over $G$ is a finite collection of terms from $G$ , where repetition is allowed and the order is disregarded. A prod…

On algebraic and arithmetic properties of monoids of product- $K$ sequences

Jun Seok Oh, Doniyor Yazdonov

Let $G$ be a group and $K$ be a normal subgroup of $G$ . A sequence over $G$ is a finite collection of terms from $G$ , where repetition is allowed, and the order is disregarded. A p…

On zero-sum problems over metacyclic groups $C_{n} ⋊_{s} C_{2}$

Jun Seok Oh, SÃ¡vio Ribas, Kevin Zhao +1

Let $G$ be a finite group. A finite collection of elements from $G$ , where the order is disregarded and repetitions are allowed, is said to be a product-one sequence if its element…

On the isomorphism problem for monoids of product-one sequences

Alfred Geroldinger, Jun Seok Oh

Let $G_{1}$ and $G_{2}$ be torsion groups. We prove that the monoids of product-one sequences over $G_{1}$ and over $G_{2}$ are isomorphic if and only if the groups $G_{1}$ and $G_{2}$ are iso…
